可能是sdk的mmz内存分配不正确导致的，修改mmz的内存大小，或者修改sample代码中使用的缓存块大小看下

都改这么大了

      2) VI->VPSS(OVERLAYEX)->VO
      3) VI->VPSS(OVERLAYEX)->VO/VENC(OVERLAY)->file
      q) quit the whole sample
sample command:3

还是不行呀！

这不对吧

自己算算这要多少内存（总的MMZ一共才128M，剩余的125M）

2592*1944*2 的VB 50个
768*576*2 的150个

总数超过 125M了，减少个数，让总数少点

memset(&stVbConf, 0, sizeof(VB_CONF_S));

stVbConf.u32MaxPoolCnt          = 32;
stVbConf.astCommPool[0].u32BlkSize = 2592*1944*2;
stVbConf.astCommPool[0].u32BlkCnt  = 5;

stVbConf.astCommPool[1].u32BlkSize = 768*576*2;
stVbConf.astCommPool[1].u32BlkCnt  = 10;

stVbConf.astCommPool[2].u32BlkSize = 768*576*2;
stVbConf.astCommPool[2].u32BlkCnt  = 10;
stVbConf.astCommPool[3].u32BlkSize = 768*576*2;
stVbConf.astCommPool[3].u32BlkCnt  = 10;
stVbConf.astCommPool[4].u32BlkSize = 768*576*2;
stVbConf.astCommPool[4].u32BlkCnt  = 10;
这个可以的！主要是总量不能太大

这个内存分配有个问题还要麻烦庄工指点一下:handshake

stVbConf.astCommPool[0].u32BlkSize，这个数组下标0指的是第一个通道么？

分配不同的下标跟把所有buf分配到0里面区别大不？而且楼主分配的不同pool分辨率还不一样。。。有点疑惑:lol

这个下标“0” 是指公共视频缓冲池的第0组，只是个index而已

不同“组”的大小可以相同也可以不同，个数可以是0个
比如：
PoolId    0    1    2    3    4    5    6    7    8    9    10    11    12    13    14    15
Size 3135488  624128 2832 3135488  624128 2832    0    0    0    0    0    0    0    0    0    0
Count    18    16    16    22    20    16    0    0    0    0    0    0    0    0    0    0

一般来说不同的pool的buffersize都会不同，但是要考虑到有些芯片的内存物理上就是分成两块的（比如Hi3531），所以会有不同pool，buffersize可能会是相同

一般来说不同的pool的buffersize不同的目的是节省内存，有点“小狗走小洞，大狗走大洞”的意思
比如VI采集主属性为15fps大小为1080P，子属性为10fps大小为1/4的1080P，这时可以开两组分别对应两种图的大小，而不是开一组大的，可以有效降低内存使用量
再比如多路解码时，需要4个1080P的vdec+12个D1的vdec，在moduleVB模式下就可以开两组分别对应两组vdec，而不用开一组大的，从而降低内存使用量
多路编码时主子码流也是同样的道理

你算一下，你分配vb已经超过总MMZ内存大小了， (2592*1944*2/1024/1024) * 50 这个都有几百兆，你的MMZ只有128M，把vb池数已经对应的块数减小
